Echo, have you used the 99, Do you think it can handle a full time post hole drilling season or two. I also have my eye on a DW SK650. There a bit pricey. But I'm a fan of keeping my back in good shape.....They are some good deals on the 650 because they have a newer model and are clearing out the old stock.

We rented one and it was great. However, we were told that heavy rock/shale is a bit of a problem. Normal ground/soil, I see no issues with it lasting a long time. When we rented it from the local hardware/rental store, they had just got it in. If we had more of a call for it Id buy one. Im not at all familiar with the 650.Posted via Mobile Device
